LEWIS J. ATWOOD, OF WATERBURY, CONNECTICUT, ASSIGNOR TO THE PLUME AND ATWOOD MANUFACTURING COMPANY, OF SAME PLACE.

SHADE-HOLDER FOR ELECTRIC LAMPS.

SPECIFICATION forming' part of Letters Patent No. 674,151, dated May 14, 1901.

I Application led October 31, 1898. Serial No. 694,999. lNo model.)

T a/ZZ whom it may concern:

Be it known that I, LEWIS J. ATWO-OD, a citizen of the United States,residin g at Waterbury, in the county of New Haven and State of Connecticut, have invented an Improvement in Shade-Holdersfor Electric Lamps, of which the following is a specification.

The object of the present invention is to obtain from a sheet-metal blank as much of the shade-holder and the clamping-ring as is consistent with strength and durability and to combine with the integral parts a separate half clamping-band that is fastened onto the integral portion at one end, and the other end slides in a mortise that becomes a guide, and a screwis employed to clamp the parts of the band to the electric light or other fixture.

In the drawings, Figure l is a plan view illustrating the present improvement, and Fig. 2 is an elevation showing the slotted portion.

The sheet-metal ring A is of proper size and shape to receive and hold the shade. It is generally provided with a flange having ears 3, through which pass the clamping-screws 4,

and there are arms 5 extending inward and integral with the ring A, and the half-band B, that is selnicircular and of approximately the proper size to correspond to the electric light or other xture to which the shade-ring is' to be applied; is integral with the arms 5, and

there is a guide 6, that is slotted horizontally similar to that in my Patent No.. 437,008 and which guide is made integral with the sheetmetal ring and formed as anintegral continuation of the extension of the half-band B.

The half-band C is aseparate piece of metal 7 and is riveted or solderedat 7 to one end portion of the half-band B, and the other end 8 of the half-band C is reduced in width and forms a finger passing through and guided by the slotted guide 6, and the screw D passes freely through a hole in one portion of the half-band C and screws into the integral extension 4L of the half-band B, so that by this 45 screw D the band portions can be set up asv required to clamp around the electric-light fixture or 4similar device, and the end 8 will move backward or forward in the slot in the y guide 6 and in this manner accommodate the 5o clamping-hand to the size of the lamp-socket or other fixture.

It is to be understood that` the integral parts are to be cut out by punches and stamped up by suitable dies into the proper shape, and in consequence of the half-band C being a separate piece from the integral half-band B the same can be of any desired thickness of metal adapted to receive the screwD and possessing the required stiness 6o and strength to clamp around the electriclight socket or other fixture, and the halfband B, having a base-ange, is sufficiently stiff to retain its shape and not become displaced in clamping the electric-light fixture, and the band C is elastic and adapts itself to such fixture in clamping the same.

I claim as my inventionl A shade-holder comprising with a sheetmetal ring and integral arms extending in- 7o ward and aI rigid half-band B integral with the arms, an integral extension of the halfband perforated for the clamping-screw and a curved slotted guide 6 integral with the shade-ring and forming a continuation of the half-band extension, and the'spring half-band .C secured to one end of the integral half-band Band having a perforation adjacent toV its free end for the clamping-screw, and reducedv n in width at its free end and said reduced end 8o passing into the curved slotted guide 6 and lthe screw for connecting and 'clamping the parts, substantially as set forth.

Signed by'me this-27 th day of October, 1898.
